The EPICS toolkit consists of a set of software components with which Application Developers can create a control system. The basic component types are:
•OPI
Operator Interface. A UNIX- or NT-based workstation or PC which can run various EPICS tools—the “clients.”
•IOC
Input Output Controller. A VME/VXI-based chassis containing a Motorola 68K or PPC processor with various VME I/O modules for analog and digital signals, and for access to field buses such as Allen-Bradley, GPIB, CANbus or CAMAC.
•LAN
TCP/IP-based Local Area Network. A communication network which connects the IOCs and OPIs. EPICS provides a software com- ponent, Channel Access, which provides network transparent commu- nication between every client—such as OPI—and an arbitrary number of servers—such as IOC.

The “who” could be anyone whether they have legitimate access or not. The “why” is simple: free computing resources, access to data, damaging your system, embarrsing the university.

IFAXVIEW is a TIFF Viewer that allows you to view Internet FAX received on the PC as a Tagged Image File Format (”TIFF”) attachment to an email.
